The world The largest and oldest icebergThe A23a has gone through the waters outside the coast of southern Georgia, a remote island in the South Atlantic, for populations of penguins and elephant stamps.
“Mega-Berg”, as it calls, is an ice sheet that is covered by about 1,500 square kilometers, but he lost about 200 miles from Antarctica to the north. In any case, the Giant trillion ton is greater than the State of Rhode Island, with a cliff tower of 1,300 meters high at certain points. It was cracked from the continental Antarctica in 1986 and Weddell was stuck in the sea, where about three decades, according to the British Antarctic Survey, polar science-based research team. The team has a station in South Georgia, the British territory as well.
The iceberg looks like a wall tower that emerges as a result of the ocean, stretched from horizon to horizon “, celurbill British Antarctica Survey Andrew Meijers Oceanographer in the notes published by the research team. Meijer studied A23a on the boat RSS David Attenborough, 2023. At the end of the year.
The A23a started wandering through the southern ocean, when the currents put in a possible course of collision with South Georgia. Iceberg and island are the same size in square mile. Researchers describe the path to South Georgia because of meandering and intriguing, because Iceberg has made an unexpected route to the island and caught it in a rotating water column last year, the month he has been canceled.

At this point, Iceberg seems to be based on the shallow shelves around South Georgia, located 50 kilometers from the southwestern coast of the island by British Antarctic Survey. Meijers, satellite images mentioned, said he is right now. But the iceberg will probably break into smaller parts and start melting at the beginning, interrupting the shipping operations and suspend the surrounding fishing.
“Berg is great, which are easily avoided by the operators of the southern ocean ships. However, as the A23’s location. However, the smaller ones are more difficult,” Meijer said. “Discussion with fishing operators suggests that large bergos have made some regions for fishing operations have more or less for a short amount of time, but often more dangerous.”
Meijer said that the A23a could have in the southern stamps and penguins, as the giant fractions of the island were surrounded by the island’s surroundings and the less food and mortality rates.
But the melting iceberg can also lead to positive environmental changes, Meijers added, to convert large numbers of nutrients to water, “actually promote populations of local predators such as stamps and penguins.”
While Meijer stated icebergs such as A23a, they are normal parts of the life cycle of Antarctica, Human climate change has accelerated the process in recent decades. 2000. Since the year, researchers recorded shelves of ice to lose about 6,000 gigatons, he said. A Gigaton 1 million tons of metric or 2.2 trillion is equal to.
“The loss of the mass of ice shelves has important consequences for adding fresh water, accelerate the rise of sea level, and possible” Punta points “, especially in Western Antarctica,” said Meijer. “These are active areas of research and active areas in Bas and anywhere else.”
